Use this form to exchange VPN information

One firewall (peer) will talk to the remote peer using their public IP, and exchange encrypted data (IPSec) in order to stablish the tunnel.
Once the tunnel is Up, the traffic will flow using their internal private address range.


Example: 10.1.50.x – 200.2.2.20 ------ (net) ----- 201.1.1.10 – 192.168.1.x:80
